What term is used in oceanography to describe the global system of deep-water ocean circulation driven by differences in water temperature and salinity?

💡 Solution & Explanation

Thermohaline circulation refers to the large-scale ocean currents driven by global differences in water temperature and salinity, which together dictate seawater density. Often described as the ocean conveyor belt, this system plays a pivotal role in redistributing heat around the planet. Other oceanographic phenomena like Ekman transport relate primarily to wind-driven surface movements rather than deep-sea density currents. Geography curricula emphasize this circulation system for its influence on global climate patterns.
